To all whom it may concern:

Be it known that we, WILLIAM A Ms BABY and WILLIAM F. LARSON. citizens of the United States, residing at New Gastleyin' the county of Garfield and State of Colo rad'o, have invented certain new and useful Improvements in Refrigerators giandwe d'o hereby declare the followingto be a full,

clear, and exact description of the int/ken;- tion, such aS willenabler others skilled in scribed, improved" means for'maintaining fresh air inthe. food chamben A further-object ofthe invention is to provide improved means for maintaining fresh and cool air in thefood-chamber.

A further object of the inventionis to provide improved: means for increasing: evaporation on the cooling element under various atmospheric conditions.

A further object of the invention is'to provide a simple, effective and economically constructed and operated refrigerator.

WVith these and other objects in view the invention comprises the improved construction, arrangement and combination of parts and devices as will appear from the following description and claims, and from the drawing submitted herewith in which the one figure is a view partly in elevation and partly in section of a refrigerator con-- structed in accordance with our invention.

The refrigerator is similar in general design to refrigerators which are in common use, being provided with a food chamber 1 with suitable shelves therein as 2, above which is a cooling chamber 3 having a lid l suitably attached to the box as by hinge 5.

Within the cooling chamber is positioned a receptacle 6 for liquid, the receptacle being made of material which will permit a slight seepage of the liquid so that the outside thereof shall be kept moist in order to provide liquid for constant evaporation. An ordinary desert bag may be used, being supported? byi any. suitable means: such as hOOks5 7 andiloopsis. .Therrbag isprovided with any suitable filling aper.-=

The wall of compartmentfixopposite par-T tition' l1 is partially. cutaway and: screened as? at 1 3 to permit'ithe passage: therethrough of the currentwof air. 7 v

There rmayzbe placed in: the compartmentzil aliquid cooling receptacleaas 114 for drinking water, the same'ha-vin'g. the usual. fillingyiaperturei .15 and: a suitable faucet lti. The-liquid container 14 1s preferably made1ofthezsame 1,

material as the container 6 and theseacontainer'sz arepreferably. :so positioned in the compartment 3 that'i thevcurrenti .a'irpassing from opening 1-2: to opening: l3-will come in cont'act-with'thermaximum amount ofsurface :of ,each. offthecontainersa =An-air .passagefll's is provided leading from the 1 lower :portionzof; the food-chamber sup;- Ward to the chamber 10 and by operation of the fan in said chamber the stale or. impure air will be drawn from the food chamber 1 through passage 17 and forced through chamber 3 across the surfaces of containers 6 and 14 causing evaporation thereon.

In order to supply fresh air to the food chamber we provide a coiled air passage 18 within the liquid container 6, the lower end of the coil projecting down into the food chamber as at 19 and the upper endof the coil connecting with the atmosphere through a filter of charcoal or other suitable substance as 20 so that when the air is drawn from the food chamber through the passage 17, fresh air will be drawn through the filter 20 and passed through the coil 18 and thence into the food chamber. The filter 20 purifies the-air and as the air passes through the coil 18 it will be cooled to the temperature of the liquid in the container 6 and as thus purified and cooled will be passed to the food chamher, this operation resulting in keeping a constant supply of cool, pure air in the food chamber.

A suitable draft regulator as door 21 fitting in opening 22 may be provided. It will be apparent that the opening of the door 21 will admit air from the outside to the chamber 10 and this will decrease the suction through passage 17.

In order that the evaporation on the surface of the containers 6 and 14 may be kept up to the desired degree in localities where the atmosphere is moist, a filter 23 of any suitable material but preferably calcium chloride may be provided within the passage 17 for the absorptionof moisture from the air passing through passage 1'? so that when the air reacheschamber 10 it will be largely freed from the moisture so that it will be effective for causing evaporation when forced across the surface of the containers 6 and 14. This filter 23 may be constructed in any suitable manner so that it may be removed from and replaced in the passage '17 easily in order that it may be removed from the passage and dried from time to time as required.- l I The cooling effect on the contained liquid, or the evaporation on the surface of the liquid containers is well known and this principle is of course in common use.

It-will be apparent that many changes may be made in the details of this construction without departing from the spirit of our invention. Y

We claim:

1. In a refrigerator, a food chamber, a liquid container, means for keepingmoisture on the surface of said container, a passage for air leading from the atmosphere through said container to said foodchamber, means for drawing air from the food chamber and forcing it over the surface of said container cooling chamber and the cooling chamber and the atmosphere, a passage for air leadving from the atmosphere through the container in the cooling chamber to the food chamber, an outlet passage forming communication between the food chamber and the compartment and a blower arranged within the compartment to create a suction from the food chamber and forcing the air through the cooling chamber causing evaporation on the container.

3. In a refrigerator, a food chamber, a cooling chamber arranged above the food chamber, a liquid container within the cooling chamber, a compartment arranged adj acent the cooling chamber, ventilating means between the compartment and the cooling chamber and the cooling chamber and the atmosphere, a passage for air leading from the atmosphere through thecontainer in the cooling chamber to the food chamber, an outlet passage forming communication between the food chamber and the compartment, a blower arranged. within the compartment to create a suction from the food chamber and forcing the air through the cooling chamber causing evaporation on the container, and means whereby to decrease the suction of air from the food chamber to be forced through the cooling chamber.
